Fig. 3From: ARFI: from basic principles to clinical applications in diffuse chronic disease—a reviewEffect of the wavelength on the speed of propagation of the shear waves. A lower SWV value (2.14 vs. 2.34 m/s) is attributed to a given target (a sphere of gel included into a phantom) using a 4.5 MHz (a) compared to a 4.0 MHz (b) transmitting frequencyBack to article page
